luminescente

I needed to contact two different entities a couple of days ago, a bus-operator and a cable tv provider, and I had to resort to their contact forms.

I got my reply, but in both cases I needed to provide further information to my initial query. One had a From: field set as no-reply@domain and the other had a admin@domain (but does not exist, as my reply was returned).

Is that hard to provide a valid From: or Reply-to: fields correctly so we can skip the contact form the second time and have some context in the email, as the previous messages are quoted in there?
